Proceedings of the Eighth Annual Deep Brain Stimulation Think Tank: Advances in Optogenetics, Ethical Issues Affecting DBS Research, Neuromodulatory …

2021

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on Septem…

Non-alcoholic Wernicke's encephalopathy: From MRI findings of a case to differential diagnosis checklist

2018

Wernicke's encephalopathy is a serious neurological disorder secondary to thiamine deficiency in alcoholics. However, rarely it affects non-alcoholics. Here we present a case of Wernicke's encephalopathy in a non-alcoholic 56-year-old female, treated by endoscopic surgery for a duodenal ulcer two years before. She came to our attention for a sudden onset of a neurological syndrome characterized by visual deficits, diplopia, confusion, spatial disorientation and loss of short-term memory. An MRI scan showed the typical MRI findings of Wernicke's encephalopathy, which are discussed together with the possible differential diagnosis.

Nursing care in therapeutic hypothermia in neonates with hypoxic-ischaemic encephalopathy. Review of the literature

2018

Abstract Introduction Hypoxic-ischaemic encephalopathy is one of the main causes of neurological damage in the new-born. Therapeutic hypothermia is the current treatment to reduce mortality and disability in new-borns with this condition. Objective To identify nursing care in new-borns with severe to moderate EHI, treated with active therapeutic hypothermia. Materials and methods A review of the scientific literature was carried out in different databases (PubMed, Lilacs, IBECS, Cinhal, OvidSP, Cuiden, Embase and Cochrane Plus) over the last five years. The documentary assessment was carried out by peers and the quality was evaluated using the CEBM and GRADE scales. Results Of the 22 articl…

From Neonatal Intensive Care to Neurocritical Care: Is It Still a Mirage? The Sicilian Multicenter Project

2021

Background. Neonatal brain injury (NBI) can lead to a significant neurological disability or even death. After decades of intense efforts to improve neonatal intensive care and survival of critically ill newborns, the focus today is an improved long-term neurological outcome through brain-focused care. The goal of neuroprotection in the neonatal intensive care unit (NICU) is the prevention of new or worsening NBI in premature and term newborns. As a result, the neonatal neurocritical care unit (NNCU) has been emerging as a model of care to decrease NBI and improve the long-term neurodevelopment in critically ill neonates. Purpose. Neurocritical care (NCC) Sicilian project includes three aca…

Machine Perfusions in Liver Transplantation: The Evidence‐Based Position Paper of the Italian Society of Organ and Tissue Transplantation

2020

The use of machine perfusion (MP) in liver transplantation (LT) is spreading worldwide. However, its efficacy has not been demonstrated, and its proper clinical use has far to go to be widely implemented. The Società Italiana Trapianti d’Organo (SITO) promoted the development of an evidence-based position paper. A 3-step approach has been adopted to develop this position paper. First, SITO appointed a chair and a cochair who then assembled a working group with specific experience of MP in LT. The Guideline Development Group framed the clinical questions into a patient, intervention, control, and outcome (PICO) format, extracted and analyzed the available literature, ranked the quality of th…

Functional brain imaging: a window into the visuo-vestibular systems

2007

Advances have been made in identifying how areas involved in processing vestibular, ocular motor, and visual information are represented in the human cortex as well as the cortical interaction between these systems in healthy subjects.While we know how some vestibular and ocular motor disorders modify visuo-vestibular interaction by changing the 'normal' cortical activation-deactivation patterns, it is still early days in functional magnetic resonance imaging studies of patients with specific disorders. Findings from current brain imaging studies of several vestibular, ocular motor, and cerebellar disorders are presented.The promise of more insights into the complex neuronal networks of the…

Pharmacological characterization and autoradiographic localization of histamine H2 receptors in human brain identified with [125I]iodoaminopotentidin…

1992

125I-Aminopotentidine (125I-APT), a reversible probe of high specific radioactivity and high affinity and selectivity for the H2 receptor, was used to characterize and localize this histamine receptor subtype in human brain samples obtained at autopsy. On membranes of human caudate nucleus, specific 125I-APT binding at equilibrium revealed a single component, with a dissociation constant of 0.3 nM and maximal capacity of about 100 fmol/mg of protein. At 0.2 nM, 125I-APT specific binding, as defined with tiotidine, an H2-receptor antagonist chemically unrelated to iodoaminopotentidine, represented 40-50% of the total. Specific 125I-APT binding was inhibited by a series of typical H2-receptor…

Cognitive benefits of exercise interventions: an fMRI activation likelihood estimation meta-analysis.

2021

Despite a growing number of functional MRI studies reporting exercise-induced changes during cognitive processing, a systematic determination of the underlying neurobiological pathways is currently lacking. To this end, our neuroimaging meta-analysis included 20 studies and investigated the influence of physical exercise on cognition-related functional brain activation. The overall meta-analysis encompassing all experiments revealed physical exercise-induced changes in the left parietal lobe during cognitive processing. Subgroup analysis further revealed that in the younger-age group (< 35 years old) physical exercise induced more widespread changes in the right hemisphere, whereas in th…

Detrimental noise effects on brain's speech functions.

2009

Background noise has become part of our everyday life in modern societies. Its presence affects both the ability to concentrate and communicate. Some individuals, like children, the elderly, and non-native speakers have pronounced problems in noisy environments. Here we review evidence suggesting that background noise has both transient and Sustained detrimental effects on central speech processing. Studies on the effects of noise on neural processes have demonstrated hemispheric reorganization in speech processing in adult individuals during background noise. During noise, the well-known left hemisphere dominance in speech discrimination became right hemisphere preponderant. Furthermore, l…
